Does thermal emissivity and solar absorptance matter for all layers?

Hi all,

I have a wall and roof section. I would like to know should I just include the thermal emissivity and solar absorptance for the innermost and outer most layers or should I define it for all of them? Furthermore, is it enough to for instance, use the solar absorptivity of white paint for a gypsum wall? Does it make sense?
